3 Claims.

This invention relates to an atomizer and more particularly to a pocket or purse type of perfume atomizer.

A number of problems are present in the design of perfume atomizers of this type that are not present in other types of atomizers. Thus, in a purse type of atomizer it is very important to provide a compact atomizer which is easy to refill and which may be operated by one hand. It is recognized that a large number of perfume atomizers have been devised from time to time, but these have not met all the above requirements or have had other objeetional features, such as being too expensive.

It is an object of this invention to provide an atomizer which not only meets the above-mentioned requirements but which has numerous additional desirable features. Thus, another object of this invention is to provide an atomizer which has a large perfume reservoir having a large ll cap which serves as the one end wall of the atomizer.

Still another object of this invention is to provide an atomizer which dispenses the desired amount of perfume in a fully atomized condition.

Still another object is to provide an improvedy mechanical construction whereby the atomizer is exceptionally durable and yet inexpensive to manufacture.

Other objects and advantages reside in the construction of parts, the combination thereof and the mode of operation, as will become more apparent from the following description.

In the drawing;

Figure 1 is a vertical sectional view showing the atomizer in its fully collapsed position;

Figure 2 is a view similar to Figure 1 but showing the atomizer in its fully extended position;

Figure 3 is a horizontal sectional view taken substantially on line 3-3 of Figure 1;

Figure 4 is a perspective view of the atomizer; and

Figure 5 is a perspective view, with parts broken away, showing the atomizer in a carry-- ing case.

Referring now to the drawing wherein there is shown a preferred embodiment of the invention, reference numeral i0 designates the main casing which is cylindrical in shape and serves as an outer housing for an inner housing Il which constitutes a combined perfume chamber and piston. A cap i2 is threaded t0 the lower end of the outer housing le and serves as a closure for the lower end of the pumping chamber which is thus formed between the inner and outer housings. A suitable gasket it has been provided, as shown, for providing a tight seal between the cap I2 and the outer housing it.

The inner housing H has its upper end closed by means of a cap i and the sealing gasket IS. An inner lining I3 is secured Within the inner housing l l and has its bottom wall and a portion of its side wall spaced from the inner wall of the housing il so as to form an air passage 23 for a purpose to be explained hereinafter. The lower end of the combined perfume chamber and piston I i serves to support a pumping element or piston seal 20 which is used in compressing air for aspirating perfume.

A spring 22 urges the inner housing I I upwardly within the outer housing It whereby a pumping action may be produced merely by holding the end of the atomizer between ones fingers and applying pressure to the opposite endy of the atomizer so as to compress air within the lower portion of the outer housing i6. As pressure is applied against the ends of the atomizer, the air trapped in the lower portion of the outer housing lll will be caused to pass upwardly through the central passage 2t formed in the cap screw 26, from whence the air will travel through the passage 28 which leads to a circular outlet opening 32 which surrounds the perfume outlet tube section 33. The upper end of the passage 25 constitutes a plenum chamber which serves to insure uniform iiow of air through all portions of the circular outlet opening 32. The circular outlet opening 32 cooperates with the outer end of the tube section 33 to form a vacuum in the tube section 33, creating a vacuum in this tube 33- to withdraw perfume. The perfume is conveyed to the outlet tube section 33 through the fluid tube or pipe 3o which has its lower end arranged adjacent the bottom of the inner housing ti and which has its upper or outlet end connected to the tube section 33. The tube section 3'3- may be formed by reducing the diameter of the end of the main tube or pipe Sil or it may be formed as a separate piece inserted into the upper endl of tube 3o. The section 33 terminates approximately .006 inch beyond the outer wall of the inner housing H, as shown.

The size and arrangement of the opening 32 is such that the escaping air serves to aspirate perfume from the perfume chamber via the tube 33 and to atomize the perfume thus picked up by the air. A vent 34' allows air to enter the' upper portion of the inner housing i l when the atomizer is in its extended position. When the atomizer is 'in its fully collapsed position, the vent 34, the

tube 30, and the air passage 32 are all sealed by means of the resilient sealing pad 36 which is held in place within the embossed cavity 38 formed in the side wall of the outer housing II) and which projects slightly beyond the cavity so as to firmly seal the vent 34 and the tube section 33.

In order to prevent relative rotation between the outer housing Ill and the inner housing II, the outer housing I is provided with an inwardly extending embossed portion 40 which cooperates with a longitudinally extending groove 42 formed in the one wall of the inner housing II, as best shown in Figure 3. By virtue of this arrangement, the sealing member 36 will always properly line up with the outlet of the tube section 33 and the vent d. The embossed portion 40 also serves as a stop for limiting the outward movement of the inner housing I I through its coaction with the washer element 44 which is firmly held against the bottom Wall of the inner housing II. Furthermore, the groove 52 provides clearance for the projecting sealing pad 36.

Since atomizers of this type are adapted to be carried by women in their purses, it is important that they be very compact and that they occupy the minimum amount of space when not in use. In the atomizer shown herein, the bottom cap I2 has riveted thereto one section 50 of a snap fastener. The section 50 supports a snap ring 52 which is adapted to snap over the bottom end of a complementary snap fastener member 54 which is held in x'ed relation relative to the bottom wall of the inner housing II by means of the cap screw 26. The snap element 54 is provided with the usual mounting flange 56 which is used for holding the washer element 58 against the piston sealing member 20. By virtue of this snap arrangement, the atomizer can be stored in its fully collapsed position when the atomizer is not in use, even though the spring 22 continuously biases the inner housing I I outwardly relative to the outer housing I0. The amount of force required to engage and disengage the snap is sufciently great so that anyone using the atomizer can pump it up and down repeatedly by the application of ordinary pressure, but in order to engage the snap element, it is necessary to exert an additional pressure.

In Figure 5 of the drawing I have shown the atomizer disposed within a, specially constructed carrying case 69. Atomizers sold in cases like the case 60 do not need to be provided with the snap elements 50 and 54, as the end walls of the case 60 are designed to hold the atomizer in its collapsed position while not in use. The case 60 is also useful with atomizers provided with the snap elements for those who do not wish to or fail to push the ends of the atomizer together far enough to engage the snap elements.

It will be noted that the case 50 consists of two halves hinged together at 62. Each end wall of the lower half consists of a narrow flange 64 which leaves the greater part of the ends of the atomizer accessible for engagement by ones fingers when removing the atomizer. The top half of the casing, which serves as a cover, is provided with end walls 56 which extend down to the end flanges 6d so as to completely close the ends of the case when the cover is shut. The hinge 62 is preferably of the well-known type which automatically biases the cover either into d the fully closed position or the fully open position. Since the details of the construction of the hinge forms no part of this invention and since hinges of this type are well-known, it will not be described in detail.

Although the preferred embodiment of the device has been described, it will be understood that within the purview of this invention various changes may be made in the form, details, proportion and arrangement of parts, the combination thereof and mode of operation, which generally stated consist in a device capable of carrying out the objects set forth, as disclosed and defined in the appended claims.

Having thus described my invention, I claim:

1. In a pocket type of perfume atomizer, an outer cylindrical housing, an inner cylindrical housing telescopically mounted within said outer housing, said inner housing having an embossed longitudinally extending groove, a nozzle carried by said inner housing and having its outlet arranged beyond the outer surface of said inner housing adjacent said outlet, an inwardly directed embossed portion on said outer housing seated in said groove and arranged in alignment with said nozzle, an outwardly embossed portion on said outer housing, a nozzle sealing means supported within said outwardly embossed portion for engaging the outer end of said nozzle in one relative position of said housings, and means for venting said inner housing including an opening the one wall of said inner housing arranged adjacent said nozzle so as to be closed by said nozzle sealing means.
